AI Technical Summary

Benefits of technology

The solution effectively reduces the sensitivity of the LCD display panel to impact damage, lowering repair costs by allowing the display to absorb and distribute forces, thus minimizing damage from drops and impacts.

Problems solved by technology

The LCD display panel is prone to damage resulting from shock loading due to impact.
Since the LCD display panel is fixed within the support frame, and the support frame is secured to the motherboard, the LCD display panel can sustain shock impact damage if the handheld computing device is struck or dropped.
Further, in view of the method by which the LCD display panel and the LCD display electronics are assembled together, typically the entire display assembly must be discarded if the LCD display panel becomes damaged.
As a result, repairs cost are often excessively high.

Embodiment Construction

[0023] Referring now to FIG. 1, there is shown a handheld computing device, denoted generally as 100, provided according to one aspect of the invention. The handheld computing device 100 includes a display 122, a function key 146 and a system motherboard 102 (not shown) disposed within a common housing. The display 122 is a self-contained peripheral device that is connected to the system motherboard.

[0024] The function key 146 functions as a power on / off switch for the handheld computing device 100, and may also function as a backlight key for the display 122.

[0025] In addition to the display 122 and the function key 146, the handheld computing device 100 includes user data input means for inputting data to the data processing means. As shown, preferably the user data input means includes a keyboard 132, a thumbwheel 148 and an escape key 160.

[0026] Typically, the handheld computing device 100 is a two-way wireless communication device having at least voice and data communication...

Abstract

A display for a handheld computing device includes a LCD display panel; a display circuit board carrying display electronics for the display panel; a cover assembly securing the display panel to the display circuit board; and a resilient layer disposed between the display circuit board and a circuit board of the computing device. The resilient layer is configured to support the display panel and to limit impact forces applied to the display panel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This patent application is a continuation of U.S. patent application Ser. No. 10 / 857,968, entitled “Handheld Computing Device Having Drop-Resistant LCD Display”, filed Jun. 2, 2004.FIELD OF THE INVENTION [0002] The invention described herein relates to a handheld computing device. In particular, the invention described herein relates to a configuration for a handheld computing device having a LCD display that is resistant to shock loading damage due to impact. BACKGROUND OF THE INVENTION [0003] The conventional handheld computing device, such as a PDA, or a wireless telephone, includes a keyboard / keypad, a display assembly and a system motherboard (not shown) contained within a common housing. The display assembly is typically provided as a reflective, transmissive or transreflective LCD display panel. [0004] To limit power losses and the effects of noise on image quality, the LCD display electronics must be disposed in close proximity ...
